So can anyone say for sure that the scroll dial issues have been fixed ? My S radio scroll dial collapsed inside the radio twice , then I paid to upgrade to an R and paid the diferance. Had no issues for about 2-4 years but now my scroll dial does not stup at the mode that I wanna go to. I've been told it may need to be cleaned by sending it back to horizon. I'm thinking just to trade it in and pay for getting the 4R but I got about 6-8 receivers. Will all my receivers work wih this new radio? I've read the thread but there is conflicting opinions on some of my questions. Another issue is that I can only drive left hand radios. I'm gonna try calling horizon to see if they can answer my questions. Its worth saying that the remote that I have been using ( my R) has been the best radio I have ever used, the functions, the feel and the performance as well. Just now for past 4 months the scroll dial has messed me up.
